WORK HOLDER EUR SEWING TIIACH'JINES.

Application filed January 10, 1923.

My invention has reference to a work holder' and feeding device tor sewing machines, and is designed particularly to hold a pad or other article to be stitched, in a manner to permit the stitching to be applied entirely around the pad and close to the edge thereof.

In stitching pads such as in garters, hose supporters and the like, it is customary to provide a holder which operates with the sewing machine to move the pad automatically in a path corresponding to the form or outline ot the stitching so that when the pad is placed in position, the machine automatically moves the pad in the. proper course t effect the desired stitching.

Pad holding` devices have been provided heretofore which engage the edges of the pad at the outer side ot the line of stitching, and thus permitthe stitching to be continued entirely around. the pad. The stitching, however. cannot be applied close along the edge of the pad owing .to the necessity of having suiiicient material extending beyond the line et stitching to be engaged by the holder. -ln some cases. tor example, in

garter and hose supporter pads, it is de-v sirable to apply the stitching so close tothe edge of the pad that there is not suiiicient material outside the line ot stitching to be engaged for holding the pad, and it has, therefore, been customary heretofore to effect the stitching` ot pads and other articles close to the edge by holding and feeding the padV or article by hand. l/Vith my machine, I provide means for holding the pad or article at the inside ot the desired line of stitching so that the stitching may be located very close to the edge of the pad or other article7 said. holder being arranged so that the stitching may be continued entirely around the holder without the latter intel-tering with or interrupting the continuity of the enclosing or surrounding line of stitching.

The principal objects of my invention are to provide a device whereby a pad. label or other article may be stitched entirely around and close to the edge; to hold a pad, label or other article within the surroundingpath of stitching so that the course of stitching ot' the needle is not interrupted or interfered with by the pad holding device; to provide a 'Heating holder within a marginal trame and supported by the latter in such a manner as to aiiiord an unobstructed Serial No. 613,702.

endless path between the holder and the frame; to provide an improved holder affording convenient access for applying and removing the work; and in generahto provide a simple and dependable work holder for a sewing machine whereby the work is automatically advanced to apply a line of stitching around and close to the edge of an article.

li have illustrated herein a particular embodiment oi my invention for edge stitching the pads of double hose supports such as are commonly worn hymen, although it is to be understood that the invention is adapted to be used for stitching pads ot various sizes and shapes by making modifications which will be readily apparent to those familiar with rthis art. In connection with my invent-ion, 1 employ automatic 'feeding mechanism for moving the pad vin a path corresponding to the particular form ot the pad which is to be stitched.y so that the stitching will follow a course around the edge of the pad. Any suitable mechanism may be employed for moving the pad in the required course.l but l prefer and have shown herein a work feed and reset mechanism pad clamp 4movernentfof the pad which is required :in

the present struct-ure.

Referring now @to the drawings, `the yretterence numeral 1 indicates a bed plate `ot' a l.Standard sewing machine, 2 :the rarm .there of and 3 the head, the latterI carrying the usual reciprocable shaft or lneedle. bar 4, calillyng ,the .needle 5 which is detachably secured in a.socket 6 atthe lower end kof the ,shaft or bar et by .the setscrew Z. rEhe shuttle sha'tvS extends under the bed plate l in the usual manner, and carries the shuttle ,9 which co-operates with the needle in forming the stitches.

Mounted on the bed plate i1are `apairof guides which engage the lateral edges 0f `a carriage 11, so that the latter `is movable .in a direction from .front to rear ot the machine, and this carriage a `pair kof spaced guides 12 arranged at right 4angles to the guides 10 l.and engaging a frame 13, which is thus'eon'tined to move trom side to side of the machine or at right Yangles to the idirection of .movement ot the carriage '1.1 as clearly shown in my prior :appli cation :above referred to. The .trame 13 is .formed with an opening which .is .internally toothed as indicated at li., and ot a form corresponding to the form of .the pad 1.5 which is to be stitched. These teeth 14T are engaged fby 4a pinion r16 on the .vertical shaft 17, which has a Worm wheel 18 thereon driven :by the Worm 1.9 :on .the shuttle shaft, so that when the machine is operated. the pinion 16 fis rotated., .and through its :engagement with the internal teeth 14 ot the frame 13 ini- .pels said frame in .a course corresponding' to `the 4torni of the pad 1.5, the universal mounting ot the iframe 13 in the guides 10 and 12, readily .permitting the required movement of .the 4trame 13. ,A cover plate 20 .is secured to Vthe top of the trame 13. and has a cam 21 on the under side which engages an axial projection 22 of the pinion 1.6 or its shaft 17 :tor holding the pinion in mesh with the internal teeth 14 of the opening in the frame 13.

Referring now to the mechanism for holding the pad, the numeral 23 indicates a. yoke which has ay bracket 241 attached thereto by the 1screws 2.5 and connected b v the screws 26 to a bracket `27, which latter is secured by Vyoke 23 and the bed ,plate 1., so lthat said .plate yis held snugly against the upper surfaceot the plate A and yet permitted to slide between the plate A and the retaining yoke 23, the latter being provided with tingers 31 which project over the lateral edges of said plate 30, and there is a frame 32 secured'onto .the upper surface lof Itheplate 30 by pins 33 or other suitable fasteners `and engaged between the fingers 31. so that 'the latter serve as .guides to control ythe sliding movement of the trame v32 and ,plate 30. The iframe 32 is provided withan openingBsl. therethrough corresponding yto the term of the pad 15 which is to be stitchethand =the plate is likewise cut-away sothat the .pad `15 ltits within the opening 34. and rests directly on the upper surface of the plate A. The 'traine 321is also cutaway as indicated at but not the plate 30, soas -to provide seats `tor the fasteners -36 which are .to be stitched onto .the pad l15. Inasmuch as the plate30 is notent away to correspond with theopenings the fasteners, when placed in the openings 35, rest upon the plate 1n hose supporters ot the type for which the `illustrated embodiment ot' my invent-ion is designed, it iscustomaryV to make them :in :pairs oi rights and .le-tts, and a strip 37 of elastic is secured at one or .the other ends ot the pad 15, depending on whether .the supporter is a right or lett supporter. To permit either arrangement the tranne 32 `is constructed at each end with .a shallow recess 38 to vreceive the end Aof the strip 37 ott elastic in proper ,position tor connection with the end of the pad 15.. .A spring` linger 439 is secured to the trame -32 as indicated Yat 40 at the inner side of each `groove 38, and projects part way across the groove 33 as shown, the end .thereof being upturned as indicated at 11, so that the strip A37 of yelastic may be inserted thereunder, and the spring finger 39 is arranged. to press upon the strip 37 suiiiciently to hold .said strip in place in the groove 38.

A cover plate 4.2 corresponding substantially in form to the holder plate 32 `is hinged at i3 to the icnner edge of the latter,

4and has an opening 114 corresponding to `the opening 34. ot the holder plate 32. This cover plate. however, is not cut .away above the seats 35, but is provided with apertures 15 located so .as to engage the buttons 46 ot the fasteners 36, which but-tons vproject somewhat above the pockets 35, and said apertures are preferably beveled as indicated by dotted lines at 47 in Figs. 2 and 3, so that when the cover plate is closed down against the holder plate 32, the apertures not only readily engage the buttons 46, but by reason of the beveled it'ormation ot' the apertures, serve to center the buttons and thereby adjust the fastener 3G to the proper position in the seat 35.

A pair of arms 48, preferably formed as a part of the plate 27, project respectively over the opposite ends ot the pad holding frame as indicated in Figs. l and 2, and each has a vertical slot 49 at th-e end which is engaged b v a lateral projection atl the upper end of the post 5l, one of these posts being secured at eac-h end oit the cover plate 42 to an extension 52 thereof.

A pair ot' `spring arms are secured to the inner ends oi the arms 48 and at the outer ends engaged over the upper ends ot the posts 5l as shown in Figs. l and 2. so as to exert a tension downwardly on the upper ends ot said posts tor torcing the projections 50 downwardly in the slots 49, and when the cover plate 42 is closed down in the position shown in Fig. 2, these springs serve to hold said cover plate in close contact with the holder plate 32. The cover plate is further held in the closed position by a spring latch 54, which is adapted to engage the inner edge ot a linger hold 55, which is secured to the outer edge of the cover plate 42.

lilith this construction which I have ust described. it will be observed that the pivotal axis ot the projections 50, while capable of vertical shitting, is held by the arms 48 against lateral movement, and the axis of the hinged connection 43, (which axis in the closed position ot the cover plate 42, is spaced laterally at the inner side of the axis ot the projections 50) moves outwardly under the pivotal axis of' the projections 50 to the outer sides thereof, as the cover plate 42 is raised. the holder plates 80 and 32 being thus slid outwardly, during the raising operation of the cover plate 42, along the surface ot the bed plate l and between the holding fingers 31, owing to the hinged con n'ection of the cover plate 42 therewith. lilith this construction the springs 53 not only allord a yielding pressure to hold the cover plate 42 closed, but when the axis of the hinges 43 passes outwardly beyond the axis ot the pins 50 also serve to throw the cover plate 42 upwardly and hold the cover plate in the upraised position.

It is not only necessary to hold the pad down in the holder 30-32 snugly against the upper surface ot' the bed plate l but it must bey engaged close along the line ot' the stitching, so that the material of the pad will be prevented from liftingas the needle is withdrawn during the operation of stitching, and, furthermore, as the'stitching is applied close to the edge ot' the pad, it is not practicable to apply holding means to the pad outside the line ot stitching. This pre sents an unusual diiculty, in view of the tact that the stitching is required to extend entirely around the pad and necessitates supporting ot' the pad clamping means in such a manner that an unobstructed path is at'- orded it'or the needle entirely around the pad. To accomplish this result, l have provided what. may be termed a floating presser plate which is carried on the cover plate 42 by members which are withdrawn from the path of the needle as the latter advances around the edge ot' the pad. rlhe presser plate which is indicated at 54, corresponds in form to the opening 44 which it enters to clamp the pad in place, but is of a smaller size to provide a narrow channel 55 between the edge oi the opening 44 ot the cover plate 42 and the marginal edge ot the presser plate 54 along which the needle operates in stitching the edge ot' the pad. Rotatable spiders are employe-d tor supporting the presser plate, two ot them, as indicated at 5G and 57, being employed in the present structure, owing to thel elongated 'form of the presser plate, which are pivoted at 7 2 to the presser plate adjacent the opposite ends thereof, and these spiders have. the extremities ot their arms engaged in sector shape guides 58 on the cover plate 42, said guides being arranged so that a. sullicient number of the arms of the spiders are engaged therewith at all times to maintain the presser plate in a fixed position with reference t0 the cover plate 42. 'lhese guides, it will be observed, form substantially circular guideways which are interrupted at the intersection of the two circular sections and also at the corners of the pads. This latter may be avoided by enlarging the circles formed by the guides so as to clear the corners but as this is not essential tor the satisfactory Operation oi the device and as it renders it possible to construct the mechanism in a compact form, I prefer with the present torni of pad to use circular guides ot the smaller circular form. Each arm ot the spider is formed on the upper surface adjacent the outer edge with a rib 59, and the usual presser toot ot the machine is replaced by a ring 60 which encircles the needle, said ring being maintained at a fixed elevation just above the upper surface ot the spider arms so that it will engage the ribs 59 on the spider arms. With this arrangement, as the machine turned and the pad holder 30-32 advanced by the hereinbefore described feeding mechanism inl a` path corresponding to thev channel 55', the spider arms which extend across the channel 55 are moved out of the way, as the needle advances, by the engagement of lOl! the ring 6() with 'the rib-59 which is ijust in advance of `the needle, the one'or the other' l' the spiders 56 or 57, as the case ymay be, being rotated on its respective pivot 72 with the outer ends oit the spider arms merely sliding along theguides 5S without altering the position ot the presser plate 5l. lll/lith the double spider construction shown, it will be apparent that only one of `the spiders is operated at a time, and as the work progresses, the ring 69 passes from engagement with one of the spiders into engagement with an arm ot the other spider, and it is necessary that the arms ot' the spiders must be arranged in proper position for the ring 'G0 to engage properly against a rib 59 as it passes from engagement with one spider to engagement with `the other. I have, theretore, designed the present structure so that the passage ot the ring '60 'trom one spider to the other leaves the spiders as shown in Figs. 2 and 3, with an arm ot' each spider in line with `or end to end with a corresponding arm of the other spider and said arms located midway Abetween the twosides ot the channel del, as Vthis insures a positioning ot' the next arm with which lthe ring 6G is to be engaged, so that said ring will properly engage. the rib ol' said arm.

In order to avoid displacement et' either spider when the ring` 60 `is not engaged therewith and to insure that the spider which is to he subsequently engaged by the ring will he maintained in position ior proper engagement by the latter, I have provided a lochinn device consisting ot' a latch member' V6l which pivoted to the cover plate l2 at (S2 and Aprovided with a not-ch 63 at each end to alternately engage corresponding ribs 59 ot the spiders 56 and 57 when the latter are in the proper inoperative position. An operating member 6l tor the lat-ch l is pivoted on the bracketV 24; at 65 and has a point or linger 6o engaging` with a notch 67 in the latch member 6l and is provided with an arcuate slot 68 which embraces the spacer .29 to permit the required pivotal movement thereo't tor adjusting the loc-hing member (il to either oi the two locking positions. pair ci'i springs e9 and 70 are connected to the outer extremity of the member Gel and entend respectively in substantially opposite directions therefrom and have their remote ends connected to a lined part on the sewing machine base l, as for example, to the op posite ends ot the nearest stationary guide l0. Vilhese springs are so arranged that when the vrorii holder is midway between the limits ot its endwise movement that is from l nt to the rear end ot' the machine)7 the tension ot the two springs 69 and 70 is the same, and the operating member (Sil is adjusted thereby to intermediate position and shifts the latchmember 6l to a corresponding position wherein the end seats G3 are both disengaged from the `ribs y590i the two spiders. This is the .rposition occupied by the pad 'holding trame as the latter is in position with the needle 5 midway between the ends of the pad, and as the ring 60 passes from engagement with one spider into engagement with the other. In view ot' the Ilined connection oit the outer ends of the springs 69 and 70, it occurs that as the pad holding trame continues to advance, the tension on one of `the springs is relaxed and the other is increased and throws the operating member trl in the proper direction to shiitt the latch. member 6l so that one of the notches (53 thereof engages with a rib 59 of the spider which has `just been disengaged from the ring 60, and this operation at the same time holds the'other notch 65 entirely disengaged from the rib 59 o1n the spider vith which the ring` 60 is coming into engagement.

'lhe presser member may l e constructed in any desired manner, but I prefer to provide same with a depending annular rim 7l as shown in Figs. 7 and S, as this insures a more eit'ective pressure on lthe pad where it is needed, that is, immediately adjacent the line ot stitching, and it also holds the plate 5l at an elevation to a'tl'ord eonvenientwconnection ot the pivotpins 72 ot the spiders with the plate.

In the progress of the stitching around the pad, there are places where the needle crosses over the thread leading to the stitcl which is being formed, and I have found that an exceedingly sharp needle will occasionally puncture the thread and thus interfere with the satisfactory operation of the device. To avoid such interference, the needle is preferably blunted very slightly so that it does not puncture the thread but detlects same at one side or the other of the needle, and I have t'ound that 'this is an ettective precaution and does not detract from satistactorystitching operation ot' the needle.

In sewing pads ot the character for which this invention is designed, it is customary Yto start the stitching at the same place on all the pads and to overlap the beginning and end portionsl et the stitching as indica-ted at 73 in Fig. Ll, the stitching being begun at the point indicated at Til in said ligure. For the purpose of permitting the overlapping ot the stitching and to reset the device at the desired starting position at the completion ot' the stitching operation, I provide a resetting mechanism oit substantially the same vform as tha shown in my application. Se-

rial No. 577,789 hereinbet'ore referred to.

T his mechanism comprises a shiltable clutch men'iher 75 on the shatt IT which is movable downwardly against the tension ot' the spring '76 to disengage the shaft and-'pinion 16 from the driving worm wheel 1S, so that the pad hold-ing trame may be freely shifted along its course of movement. A bell crank lever 77 is pivoted on the bed plate 1 to engage a roller 78 on the carriage l1 and is connected by a link 79 to operate in the same manner in the structure of my application above referred to, so that after the overlapping of the stitching` has been completed at the point indicated at 80 or at any place between the point 80 and the point 7 4, the release of the clutch 75 and depressing of thelink 79 operates the bell crank 77 against the roller 78 and forces the carriage 11 toward the front of the machine, thereby shifting the pad holder frame to the position wherein the point 74 is directly under the needle 5.

The mechanism for Operating the bell crank 77 and clutch 75 is slightly different from that illustrated in my application above referred to and comprises an arm 81 which is pivoted at one end to a bracket 82 depending from the bedV plate 1 and having the other end connected to the link 79. This arm which is normally held in the upraised position by the spring 83 has a link .811 connected to a pedal or knee operated member whereby the arm 84C is pulled downwardly at the desired time. A clutch shifter 85 in the form of a bell crank, pivoted at 86, engages the circumferential groove 87 of the clutch 75 and has a depending arm 88 engaged by a roller 89 on the pivoted arm 81. Th-e edge of the arm 88 engaged by the roller 89 is suitably formed With an elevation 90 so that the initial op-eration of the lever 81 shifts the clutch shifter 85 to disengage the clutch 75 from the Worm Wheel 18, the edge of said arm 88 beyond the rise 90 being suitably formed so as to merely hold the clutch 75 disengaged upon further movement o-f the pivoted arm 81.

In using this machine, the pads 15 are first prepared in tWo sections ready for stitching, one of Which, hereinafter referred to as the outer section, consists of a piece of stiftening material of a form corresponding to the pad and having the outer covering laid thereover With the edges turned in over the stifi'ening member and pressed so as to re main in the inturned position. The other or inner section comprises an inner covering or lining which likewise has the edges turned in and pressed. These parts are furnished to the operator of the present machine in the form just described, together With fasteners 86 and strips 37 of the elastic. The cover plate 42 is raised to the position `shown in Fig. 1, which positions the pad holder beyond the end of the machine so that it is conveniently accessible, and an inner section of the pad is laid in the opening 34 of the pad holder. A pair of fasteners 86 are placed in the seats 35 as shown and these have fabric ends Which project inwardly over the section which has been placed in the Opening 34. A strip of elastic 37 is then placed in one or the other of the seats 3.8, depending on Whether the hose supporter is right or left, and projects inwardly a short distance over the section in the opening 34, the spring 39 serving to hold it in place.

The outer section of the pad is then placed in the opening 311-. and the cov-er 4:2 closed down and secured in the closed position by the fastener 54. As the cover is closed down, the beveled openings 45 of the cover plate engage the buttons 46 of the fasteners 36 and serve to properly position the fasteners 8G, and the marginal flange 71 clamps the entire pad securely in the holder. The oper'- ation of closing the cover 12 slides the pad holder inwardly so that the point 74 of the pad at which the stitching is to be commenced is directly under the position of the upraised needle 5. `The machine is then started, and the pad holder automatically moves the pad so as to form a line of stitching entirely around and close to the edge Of the pad, the ring 60 being engaged by a rib 59 of one of the arms of the s ider 57 sothat the latter turns to affordp an unobstructed course for the advancing needle. During the first part of the stitching opera` tion, the locking member 61 is disengaged from the spider 57 so that it is free to turn, but is engaged with the spider 56 so that the latter is held against turning movement until the pad holder moves to a position such as shown in Fig. 3, wher-ein the ring 60 passes from engagement With the spider 56, Whereupon the locking member 61 is reversed and locks the spider 57 and rel-eases the spider 56. Further operation of the machine then causes a turning movement of the spider 56 as the machine continues around one end of the pad, said spider being caused to make almost a complete revolution, whereupon the spider 56 is disengaged from the ring 60 and automatically locked by the member 61 and the ring 60y again engages the spider 57 as the stitching at the other end of the pad is completed. r1`he stitching is continued after it has reached the point 74 down to or part way down to the point 8O so as to overlap the stitching at the beginning` and end of the operation. After the .stitching has been sufficiently overlapped, the machine is stopped, with the needle in the upraised position and the link 84 operated so as to pull down on the pivot arm 81, and the pad i ends, preferably employs av pair of spiders having sin arms each, as this is found `to be a satisfactory structure for this particular form of pad. rlhe present machine, however, is merely illustrative and the invention is not limited to the use of the two spiders with six arms, bnt contemplates any form or number oi spiders or holders whereby a 'floating plate orv presser member ismounted to hold to a pad during the stitching operation so as to afford a clear path around. the holder-or presser member for stitching the pad.
